T0 all whom, it may concern.'

Be it known that I, EDWARD SEITZ, a citizen of the United States,residing at Peoria, in the county of Peoria and State of Illinois, haveinvented certain new and useful Improvements in Vapor-Lamps; and I dohereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same.

lI`his invention relates to gasolene-vapor lighting-systems and pertainsto a lamp and generator therefor.

It relates more particularly to a new form of generator for producing acombustible vapor and to an automatic relief valve in connectiontherewith.

The main object herein is to provide for the generator of a vapor lamp,or for. the vapor generator, an automatic relief device for the escapeof an excess pressure of vapor in such generator and especially at suchtimes as the vapor outlet valve and the fluid supply valve are closedsuch as to retain said pressure within the generator. The result of thishigh pressure if not relieved, is to break the generator thus renderingit unit for further use and such other objects will appear herein withreference to this automatic feature as will make its value understood.

Another object is to provide a vapor lighting system in which a lampthat is used for lighting purposes also produces vapor for other lamps,that is to say, instead of providing merely a vapor-generating machineas in some of the older methods, which gives no light, my systemincludes an actual light producing lamp, that may be placed wheredesired, which produces vapor for the other lamps of the system. y

Another object of my invention is to produce a new structure for agenerator.

Figure l is a vertical sect-ion of a lamp showing my invention. Fig. 2is a longitudinal section of an automatic relief valve shown in Fig. l.Fig. 3 is a transverse seotion of a part of the same on line :c a' Fig.2. Fig. 4 is a horizontal section of the relief valve shown in the firsttwo gures. Fig. 5 is a horizontal section of a generator.

Since a system of conveying vapor to a series of lamps from a centralsource of vapor is well known, I shall not draw particular attention tothe same herein but merely refer to such parts as may be necessary toexplain the invention now under consideration.

A is a conduit for receiving vapor and for conveying it to a pipe Bwhich supplies the lamps of the system. Suitably suspended from thelower extremity of the said pipe A by means of pipe sections C and D isa needle valve E whichl discharges vapor into said pipe A through saidpipes C, D there being an air intake pipe section at F connected intothe section D the purpose of which is well known. Secured into one sideof the body of the valve'body E is a hori- Zontal tubular extension Grof a generator which consists of a retort or pot H of a hollowcylindrical form having a central vertical tubular portion J openingentirelyl through it; said retort or pot I-I having an extension Kopening into it opposite the portion G already described. The generatoris filled with a non-combustible straining material H such for instanceas asbestos as used in many lamps of this class there being two threadedplugs L in the top thereof through which the said filling can beinserted and through which said generator may be cleaned, from time totime as occasion may demand. Opening into one sideof the pipe A is apipe M whose lower end is threaded and screwed into the top of thegenerator H to communicate with the central tubular portion J of thelatter. Screwed in the bottom of the retort and also communicating withthe member J is a tube N carrying at its lower end a burner N and theusual mantle O. The extension K of the generator receives a threadedextension of a valve K to receive a supply of gasolene which enters thelatter through a feed pipe P. The fiuid enters a passage Q controlled bythe needle It. A

S indicates a passage in the valve which comunicates with the passage Q,through which the fluid passes to the generator which upon entering thelatter is heated by the mantle O or, when the lamp is first started, bymeans of asuitable torch as is well understood. The fluid upon becomingvaporized passes into the needle valve E and thence up into the pipe Ato the pipe system to supply the lamps, part of said vaporbeing dividedand forced into and down through the pipe N through the portion .I ofthe generator to the mantle. While generators are common for thispurpose the one which I illustrate herein I regard as new in form andvery efficient because of its peculiar construction and large heatingsurface. It entirely surrounds the conduit J through which the vaporpasses, so that its heat will raise the temperature of the vapor to avery high degree 'before passing to the mantle. The generator being of alarge size provides for a large heating surface so that any reasonableamount of fluid that` is supplied thereto is readily7 and quicklyvaporized and it is practically impossible for any Huid to pass into orthrough the needle valve This form of generator I believe to be novelsince it can be readily cleaned by an inexperienced person afterremoving the plug L. In co-nnection with this feature also the valve Kcan be unscrewed and removed from the extension K and a threaded plug Cscrewed into the needle valve E may be removed so that the generator canbe reached from each side through the extensions K and G thereof forcleaning purposes.

In the present invention I have provided an automatic relief valve forpermitting escape of heavy pressure from the generator and this will nowbe described. Vhile the lamp is in operation if the needle valve isclosed when it is desired to interrupt the flow of vapor to the lampcircuit to extinguish the lights the great heat resident in thegenerator will vaporize the fluid as long as any of the latter ispresent therein and necessarily if the valve R is closed the pressure ofthe vapor will run very high often `reaching a pressure of severalhundred said body K.

W which Vsurroundsthe steam V.

pounds. The extreme pressure having no way of escape results in veryoften breaking the generator and in View of this it has been my purposeto provide the automatic relief mentioned. The passage S in the valvebody K is extended beyond the stem or needle R and terminates in acavity T of A passage U connects said recess with the inlet passage Qabove the needle substantially as shown and constitutes a by-pass. Theextremity of the said passage S when it enters the said cavity T isrecessed to receive what I shall term a check valve V which is held bymeans of a spring This spring bears at one end against the head of thesaid valve and at the other against a cap X covering the valve-body K.The valvestem lies within a socket V2 of said cap and its opposite endlies in the passage S and as shown in Fig. 3 is given a form that whilecentralizing the said check valve will permit the passage of the vaportherealong into the cavity T. The passage Q is enlarged around A thevalve stem R as shownjin horizontal sece5- tion in Fig. 4 so that thevapor can pass around said stem and reach said check valve V. Now,although the valves E and R are closed the pressure from the generatorwill be relieved when sul'licient to move the valve V against itsspring. The vapor then passes ,I may use other forms that will providefor the desired result. In extinguishing the lights of the system it isnecessary rather than merely to stop the fluid supply to the generator,and let the vapor gradually burn out at the mantle of the lamps, to stopthe low of vapor at once and entirely by closing the valve E. If thevapor is permitted to gradually lessen and the light to gradually go outthe mixture of air with the vapor entering the pipe through a defectivemantle causes an explosion which ruptures all the mantles of the system.The valve R cannot be left open since the generator would be filled withfluid which would cause trouble at the time the lamps are again lighted.The necessity for some form of relief is therefore evident.

My device as distinguished from the objects of others of its classprovides for relieving pressure of vapor in the generator when thevalves are closed so that the imprisoned vapor which, as before stated,in reaching a high pressure often cracks said generator, is allowed toreturn to the reservoir of the pipe system leading therefrom. Since thevalve controlling the vapor passing toward the lamp system is closed forthe purpose stated and the valve in control. of the fluid must be closedwhen extinguishing the lights the vapor must of necessity be allowed toescape.

I have provided the usual shade for the lamp which is indicated at 2.This is sup ported from a ring 3 hung in any good manner from thegenerator extensions K-G and mounted upon this ring 3 is a casing el toinclose the lamp and give it a prescntable appearance.

My system besides the structures mentioned is novel in that, as pointedout in the objects, a lamp for producing light is used as a generatorfor the series of lamps of the system, as distinguished from a systemwherein the machine commonly employed for generating vapor provides nolight at all and occupies considerable space. My combined distributinggenerator and lamp may be suspended in any room for lighting purposesout of the way and serves a double purpose.
